Clenbuterol and the horse revisited.

This research is about Clenbuterol, a bronchodilator mostly used for treating bronchospasm in horses. The potential side effects of the drug when absorbed into the system – including major alterations in muscles and effects on bone, immune, endocrine and reproductive systems – are analyzed, with a special focus on the implications of its chronic administration.

Overview of Clenbuterol

• Clenbuterol is a beta(2)-agonist and a bronchodilator that is frequently used to treat horses suffering from bronchospasm. This medication, normally administered as a syrup, helps to open up the airways, thereby facilitating better breathing.
• Despite its beneficial effects, Clenbuterol can potentially cause several side effects once it is absorbed into the systemic circulation. The side effects are categorized into those affecting redistribution and those influencing the functioning of cardiac and skeletal muscles.

Impact on Other Physiological Systems

• Recent studies have brought to light that Clenbuterol can impact various physiological systems such as bone, immune, endocrine, and reproductive systems. A multitude of positive effects of therapeutic doses of this drug on a horse’s respiratory system have been well-documented.
• However, there is limited information available regarding the implications of chronic administration of Clenbuterol, even though it has been linked to adverse physiological effects on multiple systems.

Relevance for Clinicians and Horse Owners

• This review aims to summarize the relevant knowledge regarding Clenbuterol for clinicians and horse owners who may have to administer this drug to pleasure and performance horses.
• Therefore, this research holds importance in providing valuable insight that could improve the drug’s utilization in veterinary medicine, particularly in the care and management of horses. Hence, it will contribute to making more informed decisions on the administration and potential dangers of chronic use of Clenbuterol.
